I think the detail in the four button tiara is really beautiful but it has nothing else to it on the base or anywhere else so that's what make it look odd. If the buttons didn't stick out like a soar thumb then I think it would be ok.

The same for the six button tiara, the base is horrible and if it were set on a different frame I think it would be better looking.

That self-named "Court Jeweller" has no idea what he/she is talking about. The extermely versatile but stunningly beautiful diadem by Queen Fabiola is a classic ducal coronet. Almost any ducal family in Spain has one. The diamond fleurons can hold different coloured central gemstones. The same fleurons can be arranged into a floral wreath diadem or even a grand collier. This masterpiece of design and ingenious craftmanship does not belong in the top ten of "maddest tiaras" and in this thread with "Worst Royal Jewels". I can not taken that list au sérieux.

Any possibility that HM Margrethe will dazzle us with the poppies at the Dutch state visit?

No, she will most likely wear the Orange-Nassau pearl poiré diadem as a honour to her Dutch guests. The pearl poiré diadem was made for Princess Louise of the Netherlands (born of Prussia). A same pearl poiré diadem was made for her sister-in-law Princess Marianne of Prussia (born of the Netherlands). This means that both sisters-in-law had the same stunning diamond diadem with hanging natural pear-shaped pearls, both wearing a dazzling fortune on their heads....

The pearl poiré diadem from Princess Louise of the Netherlands (born of Prussia) ended in the Danish royal collection. The pearl poiré diadem from Princess Marianne of Prussia (born of the Netherlands) probably ended in the House of Reuss. It would have been splendid when Queen Margrethe and Queen Máxima could sit together with two identical awesome diadems which once were made for two Dutch/Prussian Princesses....

Are the golden poppies considered a tiara? To me, they look like detached hair ornaments. They're hideous, in any case.

Queen Margrethe wears the golden poppies scattered over her hair. I have seen a photoshop with these poppies arranged in a wreath, which can stand beautifully agains the dark hair of Crown Princess Mary. The same poppies can look hideous on the one and very beautiful on the other.

Well, I like the "atrocities" of the '70s. I especially like Queen Sonja's Modern Gold Tiara. I also like all the tiaras with colored stones. White diamonds are fine, but they, IMO, are quite predictable.
